Our FPGA guys keep bugging me to get their stuff in a defined state ASAP
after poweron. So "before relocation" seemed to me the best thing I
could offer to them.
To get around this would involve black magic and sacrifice of chickens
to appease them which always leaves a bloody mess on our R&D floor. So I
thought this hook might be a better option.

Cheers
